T0 at] whom, it may concern. j

Be it known that I, JOSEPH T. DROSTE, a citizen of the United States, residing at St. Louis,

State of Missouri, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. 7

My invention has relation to improvements in dumping-wagons; and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, F-igurel is a side elevation of the wagon in its normal position. Fig. 2 is a similar view with wagon-body in its tilted or dumping position, a portion of the wagont'rame being removed and parts being shown in section. Fig. 3 is a horizontal section on line 3 3 of Fig. 1. Fig. 4 is a transverse vertical section on line 4 4 of Fig. 1. Fig. 5 is a front elevation of the wagon, and Fig. 6 is an enlarged plan of the guideloop which receives the upper end of the gate-actuating lever.

The object of my invention is to construct a dumping-wagon in which the necessity for the backing of the team or draft-animals to bring the body of the wagon to the tilting position is dispensed with, the present invention contemplating the introduction of suitable gearmechanism actuated by the driver whereby the entire load is shifted to a point approximating the center of gravity thereof, thus permittingthe body of the wagon, with its contents, to be tilted rearwardly and allow the contents to be dumped at any desirable point.

A further object is to make special provision for releasing and fastening the end-gate, all as will more fully appear from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents the stationary frame of the wagon, the latter being of any approved-or conventional form and requiring no detailed description. Carried by a transverse shaft 2, disposed rearward of the middle of the length of the frame adjacent to the rear truck and located at opposite ends of the shaft within the frame, are rollers 3 3, theshaft being mounted in depending brackets 4 4. The lower longitudinal timbers 5 5, forming a part of the wagon body or box B, rest on said rollers, the body when fully drawn over the frame having additional support on the angle-brackets 6 6 and on the front truck of the vehicle, as shown in Fig. 1. at points a suitable distance in advance of the shaft 2 when the wagon-body B is in its normal positionis a transverse bar 7, about whose opposite ends are looped the outer or free ends of the diverging arms or members 8 8, formed at the rear end of the reciprocating rack-bar 9, which latter is guided by the strap 10, secured Disposed between the timbers 5 5 to the plate 11 of the frame, and by the straddie-plate 12, forming a bearing for the upper end of the axis or spindle of the gear-wheel 13, the lower end of said spindle being supported in said plate II. The gear-wheel 13 is engaged by a pinion 14 at the lower end of the staff 15, the latter being carried by brackets 16 17, projecting from the seat-supporting frame 18 and from the wagon-frame 1, respectively. The stafi is provided with a handwheel 19,which upon being turned in the direction indicated by the arrow in Fig. 3 forces the rack-bar rearwardly, carrying the wagonbody B with it, and by the time the bar 7 has passed beyond the shaft 5 the center of gravity of the wagon-body and the contents thereof will have been shifted to a point approximately over said shaft, when by a slight tilt upward of the forward end of the wagon-body the latter will readily tilt, rotating as it does about the'bar 7 as an axis and dumping the contents from the rear. 4

In the act of dumping it of course becomes necessary that the end-gate 20, normally held firmly. against the wagon-body, shall be temporarily released. The mechanism-by which the end-gate is thus controlled is as follows: Pivoted in bearings 21 21 on the front wall of the wagon-body is a U-shaped bar 22, to the free ends of whose terminal'arms are pivotally coupled the adjacent ends of the links 23 23, disposed along the outside of the sides of the wagon-body, each link having its rear end pivoted to an oscillating arm 24, the free end of said arm having also pivotally coupled thereto the forward end of a rod 25, having an outer terminal upturned end 25, from which the gate is pivotally suspended. The lower horizontal member of the bar 22 is provided with a tripping-lever composed of a lower section 26 and an upper section 26,

'pivoted thereto, the upper section being susceptible of lateral oscillation or movement and passing through and a suitable distance above the elongated guide-loop 27, carried by the front wall of the wagon-body. One side of said loop 27 is provided with an inner series of teeth or notches 28, and the base of the opposite side is provided with a single tooth 29. The section 26 has teeth 30 30, adapted to respectively engage with the teeth 28 and 29 of the loop. To retain the gate firmly against the wagon-body, the lever 26 26 is swung outwardly to the'full position, (shown in Figs. 1 and 6,) the tooth 30 engaging the forward (or any intermediate) tooth 28 of theloop, this arrangement preventing the gate from being released. To release the gate before dumping the Wagon, the driver disengages the tooth 30 from the tooth 28 of the loop by a slight oscillation of the section 26 within the loop, when by tilting the lever 26 26 rearwardly (see arrows, Figs.'1 and 6) the arms 24 are rocked rearwardly and the gate is released, as seen by dotted position thereof in Fig. 1. When thus released, it is kept so by locking the tooth 30 against the tooth 29 of the loop. (See dotted position, Fig. 6.) Now as thedriver forces the wagon-body rearwardly for purposes of dumping the wagon in the act of tilting will disengage itself from the gate, leaving the latter suspended from the rods 25, Fig. 2, said rods being temporarily supported by the forked ends of the standards 31, carried at the rear of the wagon-frame. When subsequently the wagon-body rights itself, the terminal curved guide-arms 32, carried in the rear thereof, will engage the lower edge of the suspended gate, bringingit back to the dotted position shown in Fig. 1, when the driver can again lock it firmly to the body by swinging the lever 26 26 forward and reengaging the tooth 30 with one of the teeth course, wish to be limited to the precise details here shown, as these may in a measure be departed from withoutin any wise affecting the nature or spirit of my invention.

Having described my invention, what I claim is 1. In a dumping-wagon, a suitable tilting wagon-body,an end-gate therefor, a U -shaped rocking bar pivoted along the front wall of the body, links coupled to the arms of said bar and extending parallel to the sides of the body, rearwardly-extending rods also pivotally secured to the arms, the gate being pivotally suspended from the rear ends of said rods, standards carried by the stationary portion of the wagon for the support of the rods when the body is in its tilted position, a lever secured to the U-shaped bar, and means for locking said lever in either of its extreme positions, substantially as set forth.

2. In a dumping-wagon, a suitable tilting wagon-body,an end-gate therefor, a U shaped rocking bar pivoted along the front wall of the body, links coupled to the arms of said bar and extending parallel to the sides of the body, arms pivoted to the body and connecting with said links, rearWardly-extending rods also pivotally secured to the arms, the gate being pivotally suspended from the rear ends of said rods, forked standards carried by the stationary portion of the Wagon for the support of the rods when the body is in its tilted position, a lever secured to the U- shaped bar, a guide-loop projecting from the wagon-body for the reception of the lever, and means for locking the lever at either end of the loop, the parts operating substantially as, and for the purpose set forth.

3. In a dumping-wagon, an end-gate, rods disposed along the sides of the wagon-body for the support of the gate, a swinging lever under the control of the driver, intermediate links between the lever and rods for drawing the gate firmly against the body or releasing the same, a loop for the free passage of the lever, a series of teeth or notches disposed along one side of the loop, and a basal tooth disposed along the opposite side thereof, and teeth carried by the lever for engaging the respective teeth of the loop, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH '1. DROSTE.
